Kim Kardashian has revealed that her brother Rob told her he would be bailing on her big day over email.

The reality TV star finally addressed rumours surrounding her sibling's absence from her wedding when being interview on Watch What Happens Live last night.

Host Andy Cohen questioned the mum-of-one over her relationship with her baby bro and if the two had fought when he ditched the nuptials by flying to Paris.

The 33-year-old responded: "He sent me a long email the morning of the wedding saying that he was going to leave. There was no fight."

She added: "I just thought, 'You know what, this is my day, I'm not even going to worry about it.'"

Mrs Kanye West also confirmed that her sibling decided to dart because he was feeling self-conscious about himself, specifically because of his weight.

She explained: "I totally understand that he wouldn't want to see a lot of people if he was feeling uncomfortable and you can only pray and wish that someone would not miss out on more memories in life, because life is about memories."

Well, if there was an award for the most understanding sister it would surely go to Kim.

We expected the socialite to be furious that the 27-year-old was nowhere to be seen as she walked down the aisle, but instead she only said her brother's actions 'frustrate' her.

"My brother and I are so close – he’s one of my best friends. I try to encourage him but once you don’t make that change don't for so long, I get frustrated and my patience runs out," said Kim.

"I'm definitely a tough love kind of person. If i don't like something that's going on in my life, I change it, and I don't sit and complain about it for a year."

Kim wore a skin-tight burgundy dress as she spoke about the family rift.
